Angry black smoke from muffler

I have a 94 explorer which when I drive on a long trip (4 hours) the car starts to throw black smoke from the muffler. The check engine turns on and the car starts to put..... If I stop at a light the RPM"s go down and it feels as if the car will turn off but doesn't. What can it be???

O2 sensor is my guess. The truck is running rich, hence the carbon build-up. disconnect the sensors and see if the truck runs the same or worse.
